506(b) vs. 506(c): How Private Real-Estate Deals Are Legally Offered

An investor who spends any time looking at private apartment deals eventually notices something odd. One firm publishes its offerings openly and asks for a letter from your CPA before you can subscribe. Another will discuss its strategy at length but goes quiet the moment you ask what it is buying right now, and says something about needing to know you first. Both are behaving correctly. They have simply chosen different exemptions under the same rule.

The rule is Regulation D under the Securities Act of 1933, and the two paths are Rule 506(b) and Rule 506(c). Knowing which one a sponsor uses tells you a surprising amount about how the relationship will work. This is general education, not legal advice.

Why an exemption is needed at all

An interest in an apartment partnership is a security. Selling securities normally requires registration with the SEC — the expensive, public process behind a stock offering. Registration is impractical for a $12 million apartment purchase, so Congress and the SEC created exemptions for private placements. Regulation D is the one nearly every real-estate syndication uses.

Both 506(b) and 506(c) let a sponsor raise an unlimited amount from investors without registering, provided specific conditions are met. The conditions are where they diverge, and the divergence is about one thing: advertising.

Rule 506(b): no advertising, relationships first

Under 506(b), a sponsor may not use general solicitation or general advertising to offer the deal. No public posts about the specific offering, no ads, no open webinar about the property, no listing it on a site anyone can reach. The offering may only be made to investors with whom the sponsor has a substantive, pre-existing relationship — meaning the sponsor knew enough about the person’s financial situation and sophistication before the offering existed to judge suitability.

In exchange for that restraint, 506(b) is flexible in two ways. Accredited investors may generally self-certify their status by representing it in the subscription documents. And the offering may include up to 35 non-accredited but financially sophisticated investors, though doing so triggers substantial disclosure obligations that resemble a registration statement — which is why many sponsors take accredited investors only regardless.

This is why a firm operating under 506(b) will talk about how it underwrites, what markets it likes, and what it walks away from, but will not describe a live deal to someone who joined its list yesterday. It is not coyness or a sales tactic. Discussing a specific offering with a brand-new contact is the behavior the exemption prohibits, and the waiting period exists to build the relationship the rule requires.

Rule 506(c): advertising allowed, verification required

Rule 506(c), added in 2013, inverts the trade. A sponsor may advertise an offering publicly — a website anyone can find, social posts, paid ads, open webinars. In return, two conditions bind. Every single investor must be accredited, with no allowance for the 35 sophisticated non-accredited investors. And the sponsor must take reasonable steps to verify accreditation rather than accept a representation.

Verification is the practical difference an investor feels. It typically means providing tax returns or W-2s and bank or brokerage statements, or supplying a written confirmation from a CPA, attorney, registered investment adviser, or broker-dealer — often through a third-party verification service. Investors sometimes read this as intrusive. It is the sponsor complying with the exemption it chose, and being asked for it is a sign the offering is being run properly. What accreditation actually requires is worth understanding before you reach that step.

What is identical under both

The exemption governs how a deal is offered and to whom. It says nothing about whether the deal is any good. Under either rule the sponsor files a Form D with the SEC shortly after the first sale — a short notice filing, not a review or approval of the investment’s merits. Nobody at any agency has evaluated the underwriting.

Under both, the securities are restricted and effectively illiquid: there is no secondary market, and capital is generally committed for the life of the business plan. Under both, antifraud rules apply in full — a sponsor may not mislead investors regardless of which exemption it used. And under both, the substance of what you are buying is the same set of documents: the private placement memorandum, the operating agreement, and the financial projections. Which exemption applies changes nothing about the work of evaluating the sponsor and the deal itself.

How to use this as an investor

Three practical readings. First, if you encounter a specific live deal through a public ad, it is almost certainly a 506(c), and you should expect a verification request — if none comes, ask why. Second, if a firm educates publicly but declines to discuss current offerings until you have been in contact for a while, that is the ordinary shape of 506(b), and impatience with it is misplaced. Third, if a sponsor advertises a specific offering openly and accepts self-certification without verification, that is a genuine mismatch worth asking about, because it suggests either a 506(b) being run improperly or a 506(c) skipping its central requirement.

Either way, the exemption determines how a deal reaches you, not whether it deserves your capital. Private real-estate investments carry real risk, including loss of principal, and no filing, exemption, or verification step reduces it. The diligence is still the limited partner’s own job, and it starts after the paperwork question is settled, not instead of it.
